WARNER LEWIS, OF STONE BLUFFS, INDIANA.

Tl RE-HEATING FURNACE.

SPECIFICATION forming part of Letters Patent No. 278,153, dated May 22, 1883.

Application filed February 16, 1883. (No model.)

To all whom-tit may concern:

Be .it known that I, WARNER LEWIS, of Stone Blufl's, in the county of Fountain and State of Indiana, have invented anew and Improved Tire-Heater, of which the following is a full, clear, and exact description.

My invention consists of an annular furnace with a dome having draft-regulating deflectors for controlling the heat, all as hereinafter fully described.

Reference is to be had to the accompanying suitably large in diameter to inclose an annular space, a, of suitable dimensions to receive the largest tires to be heated, and between these two brick walls I fit an annular grate, d,

on which to make the fire for heating the tires- 0, for the proper support of which above the fire I provide the arms g, projecting radially from one or the other or both of the walls.

Over the furnace a, I arrange a sheet iron dome, h, with a smokepipe, 1', at the top to carry off the products of combustion, the dome being fixed removably, and I provide a chain, j, pulley k, and lever l, or it may be any equivalent contrivance, for raising the dome when it may be required to open the furnace for the introduction or removal of the tires to be heated. The smoke-pipe will either passup through the building, so that it will rise in the hole-of the roof through which it projects, or it will have a telescopic joint at any suitable place below the root for allowing the dome to be raised properly.

At suitable intervals around the base ofthe wall 0, Iarrange draft-openingsm for the proper supply of air for combustion, and directly over these I attach deflectors n to the dome, which cover the furnace, except at the passages o, and thus cause the draft todiverge from the straight course upward and promote more uniform combustion on the grate.

At the top of the dome I arrange a damper,

p, for regulating the draft as required. Thus it will be seen that I provide a simple and efficient device naturally adapted to the peculiar form of tires, by which they can be heated much more rapidly and economically, and also better, than in the common open-air fire, and with more comfort and less labor for the operatives.

I am aware that the furnace and movabl dome are both old and not of my invention, but

What I do claim is- The furnace at b 0, having in its dome h and on its center piece, b, the deflectors n, separated by the openings o, and upwardly inclined toward the center, as and for the purpose specified.

WARNER LEWIS.
